Illustration of the galaxy fitting for two dwarf galaxies in the three optical bands, ﹩u^{\prime} g^{\prime} i^{\prime} ﹩ from left to right, respectively. The top row shows the original image, and the bottom row shows the best residual images (GALAXY—MODEL), where the nuclear star cluster is deliberately left in the center and is visible in all filters. A scale bar (solid line) is shown at the bottom left image corresponding to ﹩10\buildrel{\prime\prime}\over{.} 3\,\hat{=}1\,\mathrm{kpc}﹩.
